1. What is the enthalpy of neutralisation of a strong acid and a strong base ?

Answered by admin @ 17/08/2021

Answer:

Enthalpy changes of neutralization are always negative - heat is released when an acid and and alkali react. For reactions involving strong acids and alkalis, the values are always very closely similar, with values between -57 and -58 kJ mol-1.
